I have just started working in SSRS and I got a very strange problem i.e. When I am calling report server URL i.e. localhost/Reports
This URL requires Authentication
One Time Activity: Once you click on report it will ask again the username and password first time, to overcome this follow below guidelines.
(i) Open Internet Explorer go to Setting click on Internet options
(ii) Go to Security :-> Local Intranet -> Click on Sites
(iii) Click Advanced:
(iv) Add Site: ServerIP Addr (ex.172.16.2.224 or localhost) and then Close.
